CEA-Leti opens BCI4Stroke clinical trial, taking the WIMAGINE brain implant platform from paralysis recovery into post-stroke rehabilitation
France's CEA-Leti announced on 3 June 2026 that it has applied for regulatory authorization to begin BCI4Stroke, a brain-computer interface clinical trial extending the WIMAGINE epidural implant platform into post-stroke rehabilitation. The trial is registered on ClinicalTrials.gov as NCT07477613. WIMAGINE is the same platform that produced the 2019 tetraplegic exoskeleton walking demonstration (Benabid et al., Lancet Neurology) and the 2023 brain-spine interface paralysed-man-walks result with Gert-Jan Oskam (Lorach et al., Nature, the Courtine and Bloch programme). BrainSync is funded under France's €40 million Audace! research programme (France 2030) and the European Innovation Council under Horizon Europe.
